Have you seen the code in std.math? It is a really foul hack.

If you have a function with 3 arguments, you need to write more than 1000
function overloads. I'm not kidding. Worst code bloat I've seen in my life.

The reason why this problem with sqrt arose, is that originally, we only had
real sqrt(real), and everything was fine. Then, for reasons I don't understand, 
overloads for float sqrt(float) and double sqrt(double) were added.
Once those were added, integer arguments failed to work.

The correct solution at this stage of the language would have been to remove
those essentially useless overloads until the language can support them
properly. The only place they make any difference is when there is type
inference involved.
